Dual Freeflow Valve
Product Enquiry


  • This field is for validation purposes and should be left unchanged.

The DFFV valve operates on the discharge side of the pump. As the flow through the pipeline starts or stops, the ball automatically rises and falls, thereby opening and closing the valve. This occurs without noticeable shock or hammer,  regardless of the pressure or the speed of closure
